GAS-VALVE SHUT-OFF.

Specification of Letters Patent.

Patented Aug. 12,1913.

Application led February 17, 1913. Serial No. 748,968.

-To all 'whom t may concern.

for the purpose of cutting ott' the flow ofl gas to a building, either from the outside or from the inside, the apparatus being particularly serviceable in case of fire, whereby it may be operated by a person on the outside of a building, or, by means of afusible devices, will operate automatically in the event of fire inside the building.

The object of the invention is to produce a simple and efiicient apparatusof the kind stated. l

The invention is illustrated in the accompanying drawings in which the figure is a sectional view illustrating one form of the device.

Referring specically to the ldrawings, 6 indicates a box located 'on the outside of a building, the wall of which is'indicated at A. This boX may be provided with a breakable cover, or with any other device to prevent convenient access thereto by mischievous persons. The gas' main or .pipe supplying the gas to the building is indicated at B,and it is provided Wit-h `a valve 16 the stem of which is connected to a lever 17 which is weighted as indicated :1t-25. Q3 is a hook which, in the form shown in the figure engages a fusible eye-13 on the weight 25, the hook being pivoted at 24 to any convenient bracket or support. One arm of the hook is connected to a rope or cable 10 which extends through a p ipe 11 which communicat-es with the box 6, and at the end'the rope may have a ring 22 whereby it may be pulled. i

The hook engaging the eye 13 supports the weight and holds the valve in open position. In the event of fire, by opening the box 6 and pulling the ring 2:2 the hook is disengaged. from the weight which drops and thereby closes thevalve. Or, it lthe eye y13 is exposed to the lire it will melt and break, and thereby drop the valve.

What I claim as new is:

The combinationofa valve, a weighted operating device connected thereto, and pro.

vided with al fusible eye, a pivoted hook engaging said eye and normally held in engagement therewith by the Weight, to sustain the latter and hold the valve open, and a rope connected to the hook, to operate the same and release the weight.

In testimony whereof, I do aliix my signat-ure in presence of two witnesses.
